Clev, that post that you quoted of mine, I was referring to solid mounting the motor to the frame, and using a chain to connect the motor to the driveshaft.

What you were suggesting in that same post, is basically the equivalent of using the e-motor for a carrier bearing. This is fine, as long as the armature can stand up to the driveshaft's speeds and torque. Remember, that driveshaft gets going REALLY fast. Also, it would require less of a HP rating, and thus, a smaller e-motor, if it were chain driven with a lower gear ratio, such as the same as 2nd gear in a truck, which would still allow for most low-speed city driving scenarios, and be more efficient for said purpose, due to less weight and power requirement.
